Concept explainers
(a)
Interpretation:
Ammonia molecule has to be illustrated through ball-stick model, space-filling and two-dimensional pictures.
Concept Introduction:
Molecular geometry is the shape of a molecule predicted by considering only bond pair of electrons.
Bond angle is the angle between two bonds of a molecule and it is determined based on the electron-domain geometry.
Generally, a solid wedge bond indicates it is above the plane of the ring and a broken wedge bond indicates it is below the plane.
(b)
Interpretation:
Water molecule has to be illustrated through ball-stick model, space-filling and two-dimensional pictures.
Concept Introduction:
Refer to (a).
(c)
Interpretation:
Carbon-dioxide molecule has to be illustrated through ball-stick model, space-filling and two-dimensional pictures.
Concept Introduction:
Refer to (a).
